Fortnite

The AMD Ryzen 7 7700X paired with the Intel Arc B390 ranks 3,289 out of 3,700 tested combinations in Fortnite, placing it in the bottom 11% of all configurations. This is a decisive result: the combo sits firmly in the lower tier of performance, and the data indicates that the integrated graphics solution is the primary constraint. While the CPU is a high-end desktop part, the GPU’s integrated nature and its 9th percentile ranking among all GPUs define this pairing’s overall capability. The benchmark results show a system that can manage playable frame rates only at lower settings and resolutions, with performance collapsing as graphical demands increase.

How This Combo Ranks

The combo’s rank of 3,289 out of 3,700 places it in the 11th percentile of all tested pairings for Fortnite. This is a low position, and it aligns directly with the GPU’s standalone percentile rank of 9 among all GPUs. The data suggests that the Intel Arc B390 is the dominant factor in this ranking; the Ryzen 7 7700X, which sits at the 85th percentile among all CPUs, is not the bottleneck in this configuration. The average benchmark score for the GPU is 1,482, which is only 1.3% higher than the nearest rival, the NVIDIA GeForce GT 520MX, and 2.7% higher than the NVIDIA GeForce GT 710. This proximity to older, entry-level discrete GPUs underscores the Arc B390’s limited graphical throughput. In contrast, the CPU’s average benchmark score of 35,909 is a mere 0.3% above the AMD Ryzen 7 PRO 5845, showing that the processor is competitive with other mid-range desktop parts. The disparity between the CPU’s high percentile and the GPU’s low percentile is the defining characteristic of this combo, resulting in a system whose in-game performance is entirely gated by its graphics solution.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on Intel’s 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz. The memory configuration is entirely system-shared, with no dedicated VRAM; the data lists memory size, type, and bus width all as "System Shared," with bandwidth described as "System Dependent." This is a critical limitation for Fortnite, a game that benefits from dedicated video memory for texture streaming and high-resolution assets. The GPU’s compute capabilities are modest: it has 1,536 shading units, 48 texture mapping units, and 24 raster output units, along with 12 ray tracing cores. Its pixel rate is 60.00 GPixel/s, texture rate is 120.0 GTexel/s, and FP32 performance is 7.680 TFLOPS. These specifications, while not negligible, are far below what is required for high-fidelity gaming at modern resolutions. The GPU’s 3DMark Steel Nomad DX12 score of 1,482 confirms this, as it places the Arc B390 just 1.5% ahead of the NVIDIA GeForce 800M. In Fortnite, this translates to severe frame rate constraints, particularly at higher settings where the lack of dedicated memory bandwidth becomes apparent. The measured FPS data shows that even at 1080p Low, the average is 115 FPS, which is the highest score achieved, but this drops drastically when settings are increased or resolution is raised.

FAQ

Q: Is this combo capable of running Fortnite at 4K resolution?

A: Yes, but only at the lowest settings. The measured data shows an average of 39 FPS at 3840x2160 with Low settings. At Medium settings, the average drops to 27 FPS, and at High settings, it falls to 21 FPS. Ultra settings are not viable, with an average of 14 FPS.

Q: What is the best performance this combo can achieve in Fortnite?

A: The highest measured average frame rate is 115 FPS at 1920x1080 with Low settings. This is the only configuration that exceeds 100 FPS, indicating that the combo is best suited for 1080p gaming with reduced graphical detail.

Q: How does the Intel Arc B390 compare to its nearest rivals?

A: In the 3DMark Steel Nomad DX12 benchmark, the Arc B390 scores 1,482. This is 1.3% higher than the NVIDIA GeForce GT 520MX (score 1,463) and 2.7% higher than the NVIDIA GeForce GT 710 (score 1,443). The performance delta is very small, showing that the Arc B390 is in the same performance class as these older entry-level GPUs.

Q: Does the Ryzen 7 7700X compensate for the GPU’s weaknesses?

A: No. While the CPU is powerful, with an average benchmark score of 35,909 and a Cinebench R23 multi-core score of 19,088, the GPU’s low throughput limits overall frame rates. The measured FPS data shows that the system struggles to maintain high frame rates even at 1080p, which is a direct result of the GPU bottleneck.

Q: What are the minimum and maximum FPS values recorded for this combo?

A: The data includes min and max FPS only for the Medium settings. At 1920x1080, the average is 81 FPS with a minimum of 69 and a maximum of 93. At 2560x1440, the average is 51 FPS with a minimum of 44 and a maximum of 59. At 3840x2160, the average is 27 FPS with a minimum of 23 and a maximum of 31.

Q: Is the Arc B390’s memory configuration a limiting factor?

A: Yes, the GPU uses "System Shared" memory with a bus width of "System Shared" and bandwidth that is "System Dependent." This means the GPU relies on the system’s main memory, which is slower than dedicated GDDR6 or GDDR6X, impacting performance in memory-intensive scenes.

Measured FPS Breakdown

The measured FPS data provides a clear picture of the combo’s capabilities across resolutions and settings. At 1920x1080, the performance ranges from an average of 115 FPS on Low settings to 41 FPS on Ultra. The Medium preset delivers an average of 81 FPS, with a minimum of 69 and a maximum of 93, indicating some frame time variance but generally playable performance. High settings at 1080p produce an average of 63 FPS, which is acceptable for casual play but shows a significant drop from Low. Moving to 2560x1440, the averages fall further: Low yields 73 FPS, Medium 51 FPS (min 44, max 59), High 40 FPS, and Ultra drops to 26 FPS. At this resolution, only Low settings maintain a frame rate above 60 FPS. At 3840x2160, the performance is largely non-playable for competitive play. Low settings average 39 FPS, Medium averages 27 FPS (min 23, max 31), High averages 21 FPS, and Ultra averages 14 FPS. The data shows a consistent pattern: the frame rate halves roughly when moving from Low to Medium, and again from Medium to High, indicating that the GPU’s shading units and memory bandwidth are insufficient for higher detail levels. The gap between 1080p and 4K is stark, with the 1080p Low average of 115 FPS dropping to 39 FPS at 4K Low, a 66% reduction.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is at 1920x1080 with Low settings, which yields an average of 115 FPS. This is the only configuration that provides a frame rate high enough for smooth, responsive gameplay in a fast-paced battle royale. The Medium preset at 1080p, with an average of 81 FPS and a minimum of 69 FPS, is a viable alternative for users who prioritize visual quality over maximum frame rate, provided they can tolerate occasional dips. At 2560x1440, the Low preset is the only recommendation, as it averages 73 FPS; the Medium preset’s average of 51 FPS is borderline, and High and Ultra are not recommended due to sub-60 FPS averages. At 3840x2160, no settings preset is recommended for competitive play, as even Low averages only 39 FPS. The data suggests that users should stick to 1080p Low or Medium to ensure a playable experience, and should avoid 4K entirely unless they are willing to accept a slideshow-like frame rate. The Ultra preset should be avoided at all resolutions, as it drops to 41 FPS at 1080p and 14 FPS at 4K, making it unusable.

CPU Role

The AMD Ryzen 7 7700X is a high-end desktop processor with 8 cores and 16 threads, based on the Zen 4 architecture (Raphael) on a 5 nm process. It has a base clock of 4.50 GHz and a boost clock of 5.40 GHz, with a TDP of 105 W. The CPU’s benchmark scores are strong: a Cinebench R23 multi-core score of 19,088 and a single-core score of 1,987, as well as a Geekbench multi-core score of 12,451. In the context of this combo, the CPU’s role is to provide ample processing headroom that is never fully utilized. The data shows that in Fortnite, the frame rates are limited by the GPU, not the CPU. For example, at 1080p Low, the average of 115 FPS is a result of the GPU’s maximum output, not a CPU limitation. The CPU’s 85th percentile ranking among all CPUs indicates it is far more capable than the GPU, and its nearest rivals (AMD Ryzen 7 PRO 5845, Intel Core 7 250H) have average scores within 0.7% of the 7700X. This means that even if the GPU were upgraded, the CPU would not be a bottleneck for Fortnite at typical settings. However, the current pairing results in a significant imbalance, where the CPU idles while the GPU struggles. The CPU’s 32 MB of shared L3 cache and dual-channel DDR5 memory support (83.2 GB/s bandwidth) are more than sufficient for the game, but they do not translate into higher FPS because the graphics pipeline is the limiting factor.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals the limiting component. At Low settings, the average frame rate falls from 115 FPS at 1920x1080 to 73 FPS at 2560x1440 (a 36.5% drop) and then to 39 FPS at 3840x2160 (a 66% drop from 1080p). This scaling pattern is typical of a GPU-bound scenario, where increasing the resolution directly increases the pixel fill rate demand. The GPU’s pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are insufficient to maintain high frame rates at higher resolutions. At Medium settings, the drop is from 81 FPS at 1080p to 51 FPS at 1440p (a 37% drop) and then to 27 FPS at 4K (a 66.7% drop). The consistent percentage drops across settings indicate that the GPU is the sole bottleneck; if the CPU were the limiting factor, the absolute FPS would be similar across resolutions. The fact that the 1440p numbers are roughly 63% of the 1080p numbers, and the 4K numbers are roughly 34% of the 1080p numbers, aligns with the increase in pixel count (1.78x for 1440p and 4x for 4K). This is a clear indicator that the Intel Arc B390 is overwhelmed by higher resolutions, and the system’s performance is entirely dependent on reducing the graphical workload to keep frame rates playable. The data strongly suggests that users should stay at 1080p to get any reasonable performance out of this combo.
